The lateral or sidewalls-1 l of the" container are preferably formed. of a single blanket suitabletflexible material, suitably cut, and notched and scored along predeten -Ymined' llines of fold, a as illustrated" most 'clearly"in-Fig. 1,- of the drawin'gs, v a

a In forming theside or lateralfwalls 1 and 1 the blank is adapted'to' be folded along 7 certain predetermined lines of fold, as indi cated-bytheidottedlines at 1?; to form'the corners of the 1 container; or receptacle; one

edge ofthe blank being provided with an overlapping portion 1, adapted to extend over and to be pasted upon the adjacent marginal edge of the blank when set up.

As a convenient means of securingthe end or bottom wall to the marginal edges of the {end gussets 2 and oppositely arranged trito .extend up and, to receive the similarlyshaped marginal lateral or side walls, the blank is preferably provided at one edge with notches 1 opposite the predetermined linesof fold 1, to form the corners of the receptacle, said notches forming attaching folds 1", adapted wardly within the bottom wall folds. of {the end or bottom seetion, hereinafter referred to and shown in the drawings.

As a; means of causing the side walls to fold inwardly along predetermined lines and between the side or lateralwalls 1, theside or lateral walls 1, are preferably provided ].with amedian longitudinally extending line of folds lfi preferably formed by means of scoriiigs or creasings, thereby forming in wardly movable folds or gusset members 1, so, that when the container or receptacle is in its set up or expandedposition, as shown in Fig. l, thesame may be readily collapsed or folded by pressing inwardlyon the side.

walls 1, thereby causing theside wallgus sets 1?, tomove inwardly toward eachbther' and-between; the side walls 1, and take the position shown in Fig. 10, of the drawings.

as a means of providing an improved bot-' tom or end wall adapted to fold and unfold with the folding and unfolding move-9 mentsofthe improved lateral ,or side walls above mentioned, I provide an improved bottom or end wall 2,-prefera-bly formed of a single blank of materiahas shown in lfig; 2, of the-fdrawings the blank being provided with score orcrease lines 2 ,,extendingr -,di'agonally or from corner to corner and forming oppositely, arranged bottom or angular. shaped-bottom folds 2.

The gussets 2 and triangular folds 2,

are-adaptedtO register at their base portionszwith the side walls 'l and 1,: and as ameans of causing'the bottom or end gussets 2 to be moved simultaneously with and :to cooperate -with the side gusset-s 1 .thebottom gussets, 2", are provided with median gusset fold 2 preferably formed by; see-rings or foldings, said gusset folds 2, extending in alinement or coincident with the lateral gusset folds i It will thus be selen that the side and bottom gussets l and 2 ,-respectively, are arranged in coincident relation toeach other, so that when the latral giissets 1?, are moved in by pressure upon the side walls 1, the bottom 'or end giissets 2,,-will-be correspondingly moved inwardly and upwardly, the bottom gusset folds 2 gathering themselves upon and progressively traveling upwardly "towa ALL the apex portions of the. triangular shaped 10, of the drawings.

folds, as the sides are collapsed, as will be obvious upon reference to Figs. 7, 8, 9 and .2, being provided with cut outs or slits 2 forming attaching tabs or tongues 2,

adapted to fold over adjacent portions of 1 the folds when foldeddownwardly and to extend from the corner portions of the .re-

. ceptacle when setv up. 7

Upon reference to the accompanying rings, taken-1n connection with the foregoing description, it will be seen that the side gussets l and bottom or end gussets 2', are arranged in registering coeperative lCl'uiIlOIlrtO each other and that when the side gussets l, are moved inwardly by the side walls 1, tlie'gusset folds 2, will move upwardly over thegusset folds 1 and that the triangular folds 2, in the bottom will moveupwardly within the marginaledges of the sidewalls 1, when folded, forming a. flatand practically uniform collapsible container, as shown most clearly in Figs. 5 and 10. I

'ln forming a container or receptacle for milk the lateral or sidewalls l and l, are preferably formed in upwardly tapering or converging relation and the walls of the container ,or bottle will .be preferably. formed of preparedrsheetj material, such as paraflined paper,. or other moisture resisting .tGXllJle cheapimatei'ial. .Q

Having thus described one of the embodiments of invention, what I claim and desire to secure by Letters Patent is,

and upwardly foldable'coincident gussets respectively.

2. A container, comprising separate side and bottom walls having opposite inwardly and upwarcly'foldable coincident gussets respectively, said bottom being spacedfrom theadjaccnt ends of the-side walls and said bottom g' issets being triangular in shape and foildable over the inner base portions of said side gussets.

A flexible container having separate oppositely arranged 4 side walls connected by inwardly foldable longitudinally extending side gussets forming opposite side walls, and

upwardly foldable coincident triangular bottom grssets connected to opposite triangular bottom portions foldable Vvllilllii said gussetedand ungusseted side walls, respectively.
